DETACHABLE CLIP.

Application filed May 23,

This invention relates to detachable clips or fasteners for use in securing a number of sheets of paper or other materials together, and, although it is not limited in this respect, it relates particularly to a clip or fastener adapted to clamp together the various sheets of a newspaper, so that they can conveniently be held or turned over without becoming detached one from another.

A paper or like clip, according to the invention, includes a pair of flat parallel members hinged together about a transverse axis and a stop on one of the members adapted to engage the other so as to prevent relative movement of the members in one direction when the members are adjacent to one another. Conveniently the members are narrow members, one of them being pivotally mounted upon a bent-01f edge of a lug extending transversely from an edge of the other.

A further feature, according to the inven tion, involves spring means arranged to be operative when the members are adjacent one to another lightly to bias them to remain in adjacent position.

A preferred paper or like clip, according to the invention, includes a longitudinal member a section through which is of substantially U-shape having one arm longer than the other, a. flat strip pivotally mounted 011 the shorter arm in a manner to swing between the arms, and spring means tending to maintain the members in fixed relation when the flat strip is between the a ms. A convenient form of spring means involves a slot or in dention on one of the members adapted to cooperate with a projection or extending portion on the other member. For example, a pressed-up portion at the end of said flat strip opposite to its pivotal mounting may be provided to spring into or out of a slot at the corresponding end. of the short U-arm of the longitudinal member.

Further features according to the invention include the provision of a recess in the yoke of the longitudinal member at that end which is adjacent to the pivotal mounting for the strip, the recess accommodating the adjacent end of the strip when the same is swung with respect to the longitudinal memberinto open position. Spikes or other projections may conveniently be provided on one of the co-operating faces, for example, on the inner face of the long Uarm, and corresponding indentations may be located in the other face, the indentations being exactly opposite 1928. Serial No. 280,038.

thefree ends of the spikes when the two members are adjacent one to another. The provision of an rip-turned lug, knob, recess or the equivalent on one of the co-operating members will facilitate the openin of the clip. A further important feature resides in the provision of an extending jaw or the like on one of the members which co-operates with the other member to guide the members during relative movement into adjacent position.

It will be understood that the members should be spaced apart an amount sufficient to accommodate a certain number of sheets or layers. The spacing on different clips may be varied according to whether a clip is to be used for fastening together a largebr a less number of sheets.

For a better understanding of the invention, reference may be directed to the following description taken in connection with the accompanying drawing, in which Fig. shows a perspective view of one form of clip according to the invention, in open position; Fig. 2 a similar view with the clip closed to fasten together some sheets of paper or the like; while a Fig. 3 is a top plan view of a clip according to a modification of the invention, in open position.

Referring now to the drawings (on which like reference numerals are used to denote similar parts), and first to Figs. 1 and 2, the clip comprises two co-operating members t and 5 which are flat narrow members having parallel faces 6 and 7, between which the sheets of material 8 are adapted to be clamped. Member 5 is shown as being substantially U- shaped in cross-section having a shorter arm 9 and a longer arm 10 which provides the face 6. The shorter arm is, in effect, an offset lug secured transversely to the edge of face 6. Secured to the shorter arm 9 is the hinge means, which may be in the form of an eyelet, for example. but which is here shown in the form of a pin 11 extending inwardly towards the face 6; and pivotally mounted thereon is the other co-operating member 4.

The yoke or curved portion of the U is recessed at 12 adjacent to the hinge pin to allow of the member 4 being swung into alignment with member 5 as shown in Fig. 1. The other end of member 4 is provided with an upturned detent member 13 adapted when the clip is being closed (with the members a and 5 adjacent one to another) to pass below the surface of the shorter arm at- 14, and to spring into the slot 15, thus biasing the co-operating members to remain in this adjacent or closed position. The spikes 16 on face 6 and the co-operating indentations 17 on member 4: facilitate the gripping of the sheets 8 between members 4. and 5. Member 4 is shown as be ing provided with an tip-turned lug 18 which serves partly as a finger grip when the clip is to be opened to release the paper, and also as a guide to assist the member 4 to pass over the spikes 16 when the clip is being closed, the lug 18 and main body of member 4 forming jaws to receive the edge of the short arm 9.

In the arrangement illustrated in Fig. 3, which does not differ materially from that illustrated in Figs. 1 and 2, the free end of member 1 is slotted at 19 toprovide the grip 20, by which the opening of the clip can be facilitated, and the essential function of the lug 18 is that of guiding. In Fig. 3, also, the detent 13 is'located right at the inner edge of member 1. Moreover, in Fig. 3,.the yoke is not recessed as at 12 in Fig. 1, but instead member 1 is provided with a shoulder 21 adapted to bear on the edge of the yoke, thus limiting the opening movement of the members substantially to a right angle, as shown.

I claim 1. A fastener including a longitudinal member of substantially U-section having one arm longer than the other, a hinge means at one end of the shorter arm extending towards the longer arm, a slot in the shorter arm near the other end thereof, a flat strip mounted on the hinge means, .and a pressed-up portion on the strip adapted to spring into and out of the slot.

2. A clip comprising a longit-udinalmember of substantially U-section, one of the arms of the U being longer than the other, a hinge pin carried at one end of the shorter arm and extending towards the longer arm, a flat strip mounted on the hinge pin, recess in the yoke of the U adjacent to the hinge pin, said recess being adapted to receive the adjacent end of the strip, a slot in the shorter arm, and a pressed-up portion on the strip adapted to spring into and out of the slot.

3. A clip comprising a longitudii'ial member of substantially U-section, one of the arms of the U being longer than the other, a hinge pin carried at one end of the shorter arm and extending towards the longer arm, a flat strip mounted on the hinge pin, a recess in the yoke of the U adjacent to the hinge pin, said recess being adapted to receive the adjacent end of the strip, a slot in the shorter arm, a pressed-up portion on the strip adapted to spring into and out of the slot, and a plurality of spikes extending transversely between the co-operating faces of the said strip and said longer arm and mounted upon one of said faces.

1. A clip including a longitudinal member of substantially U-section having one arm longer than the other, a flatstrip pivotally mounted on the shorter arm, means intermediate the ends of the strip for guiding the strip to swing between the arms, and spring means tending to maintain the members in fixed relation. when the flat strip is within the arms.

5. A clip including a longitudinal member of substantially U-section having one arm longer-than the other, a flat strip pivotally mounted on the shorter arm, means intermediate the ends of the strip for guiding the strip to swing between the arms, said guiding means comprising a lug which forms with the strip a jaw adapted to receive the edge of the shorter arm, and spring means tending to maintain the members in fixed relation when the flat strip is w1th1n the arms.
